Progressive muscle relaxation (PMR) is a technique used to reduce stress and promote relaxation. It involves systematically tensing and then relaxing different muscle groups in the body. By focusing on the contrast between tension and relaxation, individuals can become more aware of physical sensations and release built-up stress. During a PMR session, a person typically starts from the feet and works their way up to the head, or vice versa. This practice can help alleviate anxiety, improve sleep quality, and enhance overall well-being by encouraging a state of calmness and mindfulness.
